Meanwhile, independent testing by accredited laboratories with globally accepted analytical methods ensures the organic extract is intact from pesticides, heavy metals, or microbiological contaminants. And reputable CBD companies have lab results from independent labs available on their websites, this can also be used as an indicator for consumers about what companies are providing high-quality CBD.
However, since the 1950s it has been lumped into the same category of marijuana, and thus the extremely versatile crop was doomed in the United States. Industrial hemp is technically from the same species of plant that psychoactive marijuana comes from. However, it is from a different variety, or subspecies that contains many important differences. The main differences between industrial hemp and marijuana will be discussed below.
If you are vaporizing CBD-dominant strains of cannabis, bioavailability is through the alveoli, tiny sacs in the lungs, clarifies Kilham. If you are taking CBD strain capsules, he suggests eating some fat or oil, like a handful of nuts or some full-fat yogurt, to improve absorption and bioavailability. Cannabinoids are fat-loving molecules. They are taken up readily into the small intestine with a bit of dietary fat.

Conversely, to preserve most of the plant’s trichromes – these are the cannabinoids, terpenes, and flavonoids – look for Supercritical (or subcritical) CO2 extraction. This method uses carbon dioxide under high pressure and extremely low temperatures to isolate, preserve, and maintain the purity of the medicinal oil. While this method is more expensive and involves complex equipment and expertise, it ensures quality.


This may seem like a repeat of an earlier question, but while that question related to concentration of CBD in the product, this is simply a question of how much you’re getting in total. Most bottles are labeled in a similar way – “1,000mg CBD Oil” or “1,000mg Hemp Extract” – which generally means the entire bottle contains a total of 1,000mg of CBD.
